SIGNALING APPARATUS FOR AUTOMOBILES ANI) THE LIKE.

Application ledctoluer 15, 1913.

To all 'whom t may concern Be it known that I, FRANCIS SCOGNA- MILLO, a citizen of the United States, residing at New York. in the county of New York and State of New York, have invented new and useful Improvements in Signaling Apparatus for Automobiles and the like, of which the following is a specification.

This invention relates to acoustic apparatus and particularly warning signals for use on automobiles, boats and other vehicles, or for anv other purpose to which the improved device may be applicable, and the primary object of the same is to provide a comparatively simple warning signal embodying a particular form of rotatable diaphragm cooperating with a iixed vibrating means therefor and operative either by direct manual actuation or through the medium of a motor device, as may be desired, to set up a vibration of the diaphragm and produce a warning tone or sound which emanates from a resonator.

The invention consists in the construction and arrangement of the several parts which will be more fully hereinafter described and claimed.

In the drawings: Figure 1 is a longitudinal vertical section through the greater portion of a warning signal embodying one form of the invention and particularly illustrating a manually operative actuating means for the diaphragm. Fig. 2 is a transverse vertical section taken in the plane of the line 2 2, Fig. 1. Fig. 3 is a transverse vertical section taken in the plane of the line 3 3, Fig. 1.

rThe numeral 5 designates an inclosing' casing which may be of any suitable form to accommodate the driving mechanism or motor means. r)The casing is secured to a recessed or chambered head 9 having a central bearing 10. The head 9 has an annular plate 12 secured over the front portion thereof and provided at the center with a circular flange 13 to receive the inner end of a resonator 14 which may be of any suitable length or contour. Rigidly secured to and extending fully across the chamber of the head 9 is a brace or support 15 which, as shown bv Fig. 3, carries at the center thereof a toothed ring or annulus 16.

The hearing has a shaft 17 rotatably mounted therein and secured to the front end of this shaft is a rotating disk 18 with Specification of Letters Patent.

serial no. 795,310.

a diaphragm 19 positively secured to the periphery thereof, the disk 18 having a forwardly projecting rim 20to which the diaphragm is secured, thereby providing a chamber 21 between the diaphragm and the bodv of the disk for the purpose of increasing' the sound or warning signal produced. The diaphragm at the center has the inner end of a vibrating arm 22 secured thereto, said arm radially extending over a portion of the diaphragm and out of contact therewith and having a projection 23 eccentrically disposed with relation to the diaphragm and in continual engagement with the toothed annulus 16 and whereby the diaphragm is caused to vibrate and give forth the warning signal desired. rl`he shaft 17 has keved on its inner end a ratchet wheel 24 which is engaged by a `spring-pressed dog 25 carried at the outer end of an arm 26 secured to a driving shaft 27 mounted in suitable bearings 28 within the casing 5. rlhe shaft 27 between the bearings 28 is provided with a screw 29. the said screw being continually engaged by the teeth or pins 30 of a pin wheel or gear 31 fast on a transverse shaft 32 mounted in suitable bearings in the casing and extending through one side of the latter and provided with an operating crank handle 33 which is adapted to be manually rotated to actuate the shaft 27. and through the arm 26 and dog 25 the ratchet wheel 24 is rotated and in turn the shaft 17, disk 1S and diaphragm 19 are similarly rotated. It will be understood that the pins 30 of the pin wheel or gear 31 coperating with the screw 29 will cause the shaft 27 to be rotated at a rapid rate of speed, and as long as the crank 33 is manuallv operated the improved device will give forth a warning signal bv reason of the proiection 23 of the arm 22 engaging the toothed annulus 16 and setting up a rapid vibration of the diaphragm 19.

One of' the main advantages of the particular form of rotating diaphragm 19 hereinbefore described is that the vibrations will be more uniformly distributed throughout the area of the diaphragm and the strain or tendency to fracture will thereby be materially reduced. By disposing the diaphragm 19 in the manner set forth or over a chamber 21, the tone or sound produced will have greater volume or be materially magnified. A further advantage is that less power will be required to produce a strong Warning signal or tone desired. Many other advantages will appear from time to time to those using the improved device, and it will be understood that changes inthe proportions and dimensions may be adopted at Will and also that the actuation or rotation of the diaphragm 19 is not dependent solely on the .mechanism illustrated for this purpose.

That is claimed is: v

In a Warning signal of the class specified, a casing having a chambered head secured thereto and separated therefrom, a resonator opening into the chambered head, a shaft mounted in the casing and having its front end projected into the chambered head, a diaphragm iiXed to the shaft and rotatable with the latter, a separate shaft in longitudinal alinement With the shaft on which the diaphragm is fixed, thediaphragm shaft having' a ratchet Wheel on its rear end Within the casing and the separate .shaft provided with a rotating vpawl, to engage the ratchet Wheel, mechanism for operating the separate shaft Withlin the casing` Vand the diaphragm shaft Vmv hand in presence of tivo subscribing witnesses.
